SBIR/STTR Phase II: Development of High Efficiency NanoFilter Media

这个小型企业创新研究第二阶段项目将使用一个原型设计来证明静电纺丝生产纳米纤维的商业可行性。纳米纤维将与传统的过滤介质相结合，形成一种用于液体和空气过滤的新型纳米过滤器。这些应用已被证明可以从流出流中去除小于3微米的颗粒，具有卓越的过滤效率和诱人的成本潜力。丙烯酸纳米纤维将被静电纺成纳米网，直接附着在传统的支撑（过滤介质）基板上。网将与保护层结合，形成三明治结构，收集成卷。通过改变结构：衬底、纳米纤维直径、纳米网密度和纳米网厚度，可以很容易地定制过滤器，以达到所需的复合过滤器性能。该项目将与学术中心和大型企业作为战略合作伙伴共同开展。未来几年发展起来的纳米技术将为一个重要的商业平台奠定基础。在各种过滤过程中的商业应用，如：高端工业原料净化，生物分离，超纯空气和水系统，医院洁净室，农业和食品工业过滤器，以及微电子行业的下一代清洁环境需求。

This Small Business Innovation Research Phase II project will demonstrate using a prototype design the commercial feasibility of electrospinning to produce nanofibers. Nanofibers will be combined with conventional filter media to form a novel NanoFilter media for liquid and air filtration applications. These applications have been shown to remove particles smaller than 3 microns from effluent streams with superior filtering efficiency and attractive cost potential. The acrylic nanofibers will be electrospun as a nanoweb directly on to a conventional support (filter media) substrate. The web will be combined with a protective cover layer to form a sandwich structure, which will be collected as a roll. The filter will be easily tailored to achieve the desired composite filter performance by varying architecture: substrates, nanofiber diameter, nanoweb density, and the nanoweb thickness. This project will be carried out collaboratively with academic centers and major corporations as its strategic partners. Nanotechnologies developed in the coming years will form the foundation for a significant commercial platform. Commercial applications in a variety of filtration processes such as: high-end industrial raw material purification, biological separations, ultra pure air and water systems, hospital clean rooms, agriculture and food industries filters, and microelectronic industries next generation clean environment needs are anticipated.
